The term Navajo Wars covers at least three distinct periods of conflict in the American West: the Navajo against the Spanish ; the Navajo against the Mexican government ; and the Navajo against the United States. These conflicts ranged from small-scale raiding to large expeditions mounted by governments into territory controlled by the Navajo. The Navajo Wars also encompass the widespread raiding that took place throughout the period; the Navajo raided other tribes and nearby settlements, who in return raided into Navajo territory, creating a cycle of raiding that perpetuated the conflict.

Alexander William Doniphan was a 19th-century American attorney, soldier and politician from Missouri who is best known today as the man who prevented the summary execution of Joseph Smith, founder of the Church of Jesus Christ of Latter Day Saints, at the close of the 1838 Mormon War in that state. He also achieved renown as a leader of American troops during the Mexican–American War, as the author of a legal code that still forms the basis of New Mexico's Bill of Rights, and as a successful defense attorney in the Missouri towns of Liberty, Richmond and Independence.
